What is vacuum blast equipment

Have already visited: 90707/29/2019  

The vacuum blast equipment is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base, drip nozzle. The vacuum blast equipment is operated eccentrically by the rotor biased in the cylinder, and the volume change between the blades in the rotor groove sucks, compresses, and discharges the air. In operation, the pressure difference of the blower is used to automatically send the lubrication to the drip nozzle, drip into the cylinder to reduce friction and noise, and keep the gas in the cylinder from flowing back. This vacuum blast equipment is also called a vane blower.

The vacuum blast equipment is a volumetric operation blower because the impeller runs in the machine without friction and does not require lubrication. When used, the flow changes very little as the pressure changes. But the flow varies with the speed. Therefore, the choice of pressure is wide, and the choice of flow can be achieved by selecting the speed. The structure of the vacuum blast equipment determines that its mechanical friction loss is very small. Because only the bearing and gear pair have mechanical contact on the material selection, the rotor, casing and gear ring have sufficient mechanical strength. Safe operation and long service life are a major feature of blower products.
